Moodle plugins directory: Auto Attendance

This autoattend block is modification of the Attendance block by Mr. Dmitry Pupinin (v1.0.8, 2007).
In addition to the original manual mode, automatic attendance mode (from the access log of Moodle) and semi-automatic attendance mode (user clicks a link) are also possible.

These Auto Attendance block and module are modification of the Attendance block/module of Mr. Dmitry Pupinin (v1.0.8, 2007).

In addition to the manual attendance mode to take attendance manually the original, automatic attendance mode (from the access log of Moodle) and semi-automatic attendance mode (user clicks a link) are also possible.

Just so anyone having the same issue as me (Potential coding error - existing temptables found when disposing database. Must be dropped!) when doing a backup, you must have both the block and module installed to be able to backup a course. We get the functionality we want with just the block, so I wish there was a way to use the plugin without the module installed!

I would like to ask you what do you do in relation to summer time (daylight saving time)?
I discovered that if I create sessions that - cross the date where we are supposed to reset the clock - all sessions are pushed one hour forward.
(That is in the Fall - in the spring sessions will be moved one hour later than intended).

If I take this into account and compensate this hour - will the "session start" remain correct when we pass 30th of October 2016?

Have a issue that if I have a student unenroll from a class, I am no longer able to access their attendance record up to the day they dropped the class (unless I add them back to the class).

I have tried leaving them enrolled (but suspending them) but they still show up on future attendance sheets. Also tried putting them in different attendance classes (or the excluded class) but than I still end up loosing all of their attendance.

Easiest solution I can think of is for Auto Attend to mark students with a 'Suspended' status as 'Not Called'. Can this be done?

Thinking about this further, Suspending a student won't work in the scenario of a student changing courses... Is there another way a students attendance can be stored/viewed if they are no longer enrolled in a class?

This is a great plugin but
I have 2 problems with this plugin
We use Moodle 3.3
1)
when we set multiple sessions for about a year from now, a certain hour once a week (let's say 14:00) we get all sessions fine until March, then after March (when our clocks moves 1 hour forward - summer time) all sessions set to 15:00 (1 hour forward) instead of 14:00 .
How can we fix this problem?
We have correct timezone setting in php.ini Asia/Jerusalem (in our case) .
Everything in our Moodle (assignments\quizes) with dates and time works just fine except this issue in this plugin.
Any change I can do in the code?

2)
When I try to click on the "P" link ( Present) so all student will be present with the radio buttons - nothing happens (see image), no respond
(in Moodle 2.9 this issue works fine).
